A dissipative beach is characterised by

  • A.coarse sediment, a steep slope and plunging breakers
  • B.no wave action reaching the shoreline at all
  • C.a cliff descending directly into deep water
  • D.fine sediment, a gentle slope and a wide surf zone

Answer: D

Wave energy is spread over a broad zone and released gradually as spilling breakers. Reflective beaches at the other extreme concentrate the energy into a narrow steep face. The two ends of the range behave very differently.
